Astrobiology is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events. [2] As a discipline, astrobiology is founded on the premise that life may exist beyond Earth.
Cellular compartments in cell biology comprise all of the closed parts within the cytosol of a eukaryotic cell, usually surrounded by a single or double lipid layer membrane. These compartments are often, but not always, defined as membrane-bound organelles. The formation of cellular compartments is called compartmentalization .
Skeletal muscle fibers are classified into two types: type 1 and type 2. Type 2 is further broken down into subtypes. Type 1. These fibers utilize oxygen to generate energy for movement. Type 1 ...

Epidermis – Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue – The primary components of vascular tissue are the xylem and phloem.
Surface anatomy. Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of surface anatomy. Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. [1] In birds, this is termed topography.
